ROLLING-MILL.

SPECIFICATION forming part of Letters Patent No. 694,025, dated February 25, 1902.

Application filed June 25, 1901. Serial N0.65,917. (N0 model.) I

To all whom it may concern:

Be it known that I, ZACHARIAH \VEBB ONIONS, a subject of the King of Great Britain, residing at Wainfelin, Pontypool, in the county ofMonmouth, England, haveinvented new and useful Improvements in Rolling- Mills, (for which I have made application for patent in Great Britain under No. 7,755, bearing date April 16, 1901,) of which the following is a specification.

Myinvention relates primarily to that class of rolling-mills now known as continuous mills, in which the piece of metal being rolled passes on through a series of successive rolls in front of each other without the intervention of manual labor. In such mills, where all the rolls have their axes in the same plane, it is found necessary to provide means by which the piece during its travel from the pass in the one pair of rolls to the pass in the next pair of rolls shall be turned over at right angles, so that the fin formed at the joint-surface of the one pair of rolls shall fall in or about the solid bottom of the pass of the succeeding pair of rolls. Also the difficulty of turning over the piece between two pairs of rolls has been avoided by having the axes of each succeeding pair of rolls placed transversely'to those of the preceding pair. Such an arrangement, however, is-open to many objections.

Now the object of-this my invention is to provide an improved arrangement of rolls whose axes are all parallel to each other and so disposed that the piece of metal being rolled may pass on from rolls to rolls without the necessity of being turned over. I attain this object by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a side view of two pairs of rolls arranged according to this my invention. Fig. 2 is a front view of my invention, showing a leading pair of rolls, Fig. 3 is a front view of my invention, showing a succeeding pair of rolls to receive the piece from the previous pair.

Similar numbers refer to throughout the several views.

Two pairs of rolls only are shown on the drawings; but any required number may be used. The rolls have their axes in the horizontal plane and are all parallel to each other, rolls 5 and 6 forming one pair and rolls 7and 8 forming a succeeding pair. In each roll an similar parts inclined surface 9 is provided to agree with each other as a pair and at an angle of fortyfive degrees, or thereabout. It will be seen that to provide these surfaces 9 the enlarged used in the same pair of rolls, two of such being illustrated. In these surfaces the passes 10, 11, 12, and 13 are made, and it will be noticed that the finning-joint in pass 10 is at right angles to the inning-joint in the succeeding pass 12. The disposition of the pass in each succeeding pair of rolls is thus alternated, so that the fin from one pair is made to avoid the [inning-joint in the succeeding pair. It will therefore be obvious that by means of a suitable guide to convey the piece from one pair of rolls to the next the piece may pass on throughout a given series without any turning over or furtherattention. I have illustrated the passes as of a somewhat diamond shape as being most convenient for explanation; but'such sectional shapes will be varied to suit requirements. The rolls may be driven and adjusted by any of the well-known suitable means. Two or more of such continuous pairs of rolls may be used as a complete mill or in conjunction with other forms of finishing-mills, according to sections of'rolled material required. 1 I am aware that continuous trains of rolls have already been made whose successive passes have been axially disposed in opposite inclined directions, and therefore I "do not claim such broadly; but

What I-claim, and desire to secure by Letters Patent, is

In acontinuous-roll train having upper and lower rolls whose passes are successively placed axially in opposing inclined positions,

such passes having the initial inclined, surfaces 9 as shown on the drawings and for the purposes specified.
